When Dad, an electrician, had to do it he pulled the wire through
the conduit before installing it - goes through the bends and LBs
a lot easier that way. Using stranded wire involves junction
boxes and joints when transitioning from "protected by conduit"
to "not requiring protection" or "protected by existing structure"

You are quite correct in that, but it's not a big deal to hang the
boxes and tie in inside them. Using THHN offers many advantages
over pulling NM through conduit, and makes the transition matter of
little real value.

Residential electriciand don't usually have rolls of individual wire
on the truck as (at least here in Ontario) it is VERY seldom used -
and was used even less back before Dad retired.

I'd be surprised if residential electricians did not have THHN on
the truck. There are times and places for it even in residential
wiring. If they don't - Home Depot is just down the road. I'll
agree that it is not a significant percentage of residential wiring,
but it's not at all an uncommon occurrance, either. No matter - for
the job at hand, any residential electrician would not find it
unreasonable to use conduit and THHN in a given application. I
don't know when your dad retired, but I've been wiring for over 25
years, and I'm way older than that implies, and I've seen plenty of
conduit with stranded wire that pre-dates my arrival on earth.

Pop is 82 next week. He retired when Mom died - that's 20 years ago
now.
Here in Ontario, very little conduit was/is used in residential other
than main power feeds. Not much 12 or 14 guage undividual cable, and
less yet in stranded (flexible) wire that small.

The main use of conduit was protection on concrete basement walls,
where the junction box would be inaccessible if a cieling was
installed, making an illegal concealed junction.
Running romex directly into the EMT strapped to the wall eliminated
the connection, making it fully code compliant, and legal. (even if
the cable entered the conduit through a box - as long as there were no
connections in the box)

Of course, if there was an issue with pulling the romex, the sheath
could be stripped off, producing separate conductors to pull through
the conduit. - again with no connections in the box.
Impractical for mor than 6 or 8 feet

I have to say, regardless of whether we get to any further point of
understanding on this little piece of this thread, I am finding that I am
enjoying your posts in this thread. I'm enjoying the way your talk about
"dad", "mom", etc. Screw all the other details - I'm just enjoying reading
your responses. That probably does nothing to advance this thread, but I
don't really care. Just enjoying what you're writing.
